[Inhibitory effects of RNA interference on MMP-24 expression and invasiveness of ovarian cancer SKOV(3) cells]

To investigate the inhibitory effect of RNA interference (RNAi) on MMP-24 expression and invasiveness of ovarian cancer SKOV(3) cells.Two pairs of small interfering RNA (siRNA) specific to MMP-24 mRNA were designed and transfected into SKOV(3) cells. RT-PCR and Western blotting were used to detect the mRNA and protein expressions of MMP-24, and the cell invasiveness was assessed using an in vitro invasion test.After transfection with siRNA, the mRNA and protein expression levels of MMP-24 were obviously reduced in SKOV(3) cells, which also showed significantly decreased invasiveness in vitro.MMP-24 gene silencing by RNAi can suppress the invasiveness of ovarian cancer SKOV(3) cells in vitro, which may provide a new therapeutic approach of ovarian cancer.
